Just a quick question and wondering if others have seen this. I went and left a comment on a blog. A few days later I noticed in GWT on the 'Links To Your Site' part that I had a couple hundred links from the blog domain. In GWT it's 1 linked page with total links in the hundreds. On Ahrefs I can see where the links spiked up and slowly fell off throughout a 3 month time span on the graph. After a while the GWT numbers fall down as well. I've always wondered why this happens. I just had a new site go one day from 7 links to over 100 and the majority are from one domain where I left a single blog comment. No other linkbuilding done at the time. Just curious if any others have seen this? Cheers!
